Finding the right fit matters, especially for a piece you'll wear every day. Use one of the methods below to find your US ring size.
Method 1: Measure a ring you already own

- Find the closest diameter in the chart below.
Method 2: Measure your finger
- Wrap a thin strip of paper or string around the base of your finger.
- Mark where the ends meet and measure the length in millimeters. This is your circumference.

Tips for the best fit
- Measure at the end of the day, when fingers are slightly larger, and avoid measuring when your hands are cold.
- If you're between sizes, choose the larger size.
- Wide bands fit tighter than thin bands; consider going up half a size for a wide band.
- Make sure the ring slides over your knuckle comfortably.
